ABSTRACT:
One exemplary embodiment can be a process for increasing an efficiency of an acid gas removal zone. The process can include sending a sour gas stream including at least one gas to a first absorber providing an overhead stream absorbing the at least one gas; withdrawing a side-stream from the first absorber and passing the side-stream through a holding tank, a side-stream fluid transfer device, and a side-stream chiller before returning the side-stream to the absorber; and passing the first absorber overhead stream to a pump-around circuit for a second absorber. Usually, the pump-around circuit may include a flash drum, a pump-around fluid transfer device and a pump-around chiller before providing a slipstream to the first absorber and another portion to the second absorber.
